I think 135 is a great starting point. Any less than that can be put in the racks, but most people I have seen are fine starting with 135. I personally think it is a good idea to squat for a little while before deadlifting. Once you have pretty good squat form, then learn the deadlift. I don;t like to teach serious beginners too much at one time, focus on one thing at a time. Once they have squatted a little bit, then deadlifting 135 probably will not be a problem. Form first and then they can move up in weight.

Maybe this is just the way I learned it, but I squatted for probably a few months before ever even attempting a deadlift. And then I was fine starting at weights around 185-200.
